- Threat detection for known trackers (AirTag, Tile, SmartTag, Chipolo)
- WiFi camera pattern detection
- Real-time SSE streaming for sweep progress
- Futuristic circular scanner progress visualization
- Unified threat dashboard with severity classification

New files:
- routes/tscm.py - TSCM Blueprint with REST API endpoints
- data/tscm_frequencies.py - Surveillance frequency database
- utils/tscm/baseline.py - BaselineRecorder and BaselineComparator
